Feature
- High chemical resistance and dielectric strength
- Residue-free removability for masking applications
- High temperature resistance (up to 260°C)
tesa® 4428
tesa® 4428 is a standard grade polyimide tape with a silicone adhesive that has been specially developed to provide a solution for applications which require high temperature and chemical resistance. tesa® 4428 is used for various applications, especially for wave soldering, thermal insulation and cable wrapping as well as masking during powder-coating processes where the tape enables sharp color edges and offers excellent paint anchorage. The polyimide tape’s silicone adhesive system makes the tape extremely heat-resistant, withstanding extreme temperatures of up to 260°C in continuous applications.
Application
- tesa® 4428 is recommended for high temperature masking, e.g. powder coating, galvanizing
- The standard grade polyimide tape can be used for chemical production processes and wave soldering, e.g. during circuit board assembly
- Suitable for masking of 3D printing beds or electrical and thermal insulation, e.g. wire-or cable-wrapping
